1999-2004 6.8L SUPER-DUTY PICKUP: Banks has the formula for building V-10 muscle: the stainless-steel PowerPack adds best gains of +56 hp, +67 lb-ft torque, and 7% more miles to the tank-full. A pair of bulletproof TorqueTube manifolds uncorks major torque for big hauling and climbing jobs. Banks optional electronic AutoMind engine-calibration module maximizes power while keeping a stern check on the air-to-fuel ratio, for safe exhaust temperatures and engine longevity. Vehicle is EGR-equipped (1999 models only) if there is a large hex fitting connecting steel tube to exhaust manifold on driver's side. To identify type of catalytic converter, locate flange between Y-pipe and cat converter: Early style cat converter--flange behind transmission cross-member. Late style cat converter--flange in front of transmission cross-member. Systems do not fit 2005 (3-valve) vehicles--designated by a V in the 8th position of the VIN number. PowerPickle. Banks invented a ballistic flow device to overcome the problem that occurs where tubes join within a single collector (a dead zone that kills exhaust-gas velocity). The patented PowerPickle fills that void and utilizes the rotational firing order to maximize exhaust extraction. This detail-exclusive to Banks-captures exhaust-gas action and turns it into massive torque.
